Quotes from Yogācārabhūmi-Śāstra, Vol.53
“For what purpose are the various aggregates established? That is, all forms, from the distant past to the recent and current lifetimes, the form aggregate, including consciousness and other aggregates. As such, these are all briefly subsumed under the mode of aggregates. Accumulation denotes the principle of aggregates. Furthermore, all the various aggregates merely have myriad names, specific characteristics, and all compounded phenomena. In light of this, we should understand that the purpose of setting up various aggregates is to manifest the no-self (selfless) nature of all aggregates.”
《瑜伽師地論》卷五十三
「為顯何義建立諸蘊？謂所有色，若去來今乃至遠近，如色乃至識亦爾。如是總略攝一切蘊。積聚義是蘊義；又由諸蘊唯有種種名性諸行，當知為顯無我性義建立諸蘊。」
